| 20080292526 | Method for the Production of Double Metal Cyanide Complex Catalysts - Process for preparing double metal cyanide catalysts of the general formula (I) | 11-27-2008 |
| 20090099361 | NOVEL TANTALUM AND NIOBIUM COMPOUNDS - The present invention relates to specific, novel tantalum and niobium compounds which can serve as starting materials for the preparation of chemical vapour deposition (CVD) precursors. | 04-16-2009 |
| 20090275771 | Process for the preparation of urethanes - Urethanes are prepared by oxidative carbonylation of at least one amino compound in the presence of carbon monoxide, oxygen and organic, at least one hydroxyl-group-carrying compound. The carbonylation is carried out in the absence of halogen-containing promoters. The carbonylation is also carried out in the presence of a metal complex catalyst which contains neutral bidentate N-chelate ligands of the (N˜N) type, two monoanionic N,O-chelate ligands of the general type (N˜O) | 11-05-2009 |
| 20090298189 | Hydrophobic Ionic Liquids - The subject of the invention at hand are novel, a little basic, fluorinated pentafluorophenyl imide anions, which can be used as anions in ionic liquids. Methods for producing ionic liquids are described, which contain these novel pentafluorophenyl imide ions as anions, as well as quaternary organic ammonium ions, guanidinium ions, N-organo-pyridinium ions, imidazolium, imidazolidinium or benzimidazolidinium ions, alkyl-alkylidene phosphoranes or aryl-alkylidene phosphoranes as cations. Alternative methods according to the present invention provide ionic liquids through reaction of ketene N,N-diacetals or alkyl or aryl-alkylidene phosphoranes with acids. | 12-03-2009 |

| 20110034713 | Ortho-metalated, chelate-stabilized benzylamines of the rare-earth metals (RE) Ar3RE - The present invention describes homoleptic, ortho-metalated, chelate-stabilized benzylamine complexes of the rare-earth metals. The rare-earth metals are selected from Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu. In the complexes according to the present invention, at least one benzylic proton of the benzylamine ligand is replaced by an alkyl or aryl group. Such complexes are preferred in which both benzylic protons of the benzylamine ligand are replaced by an alkyl- or aryl group. The complexes according to the present invention are produced by reaction of chelate-stabilized rare-earth metal halides with ortho-lithiated aryl ligands at room temperature under inert gas atmosphere. The complexes according to the present invention are thermally stable and suitable for being used as catalysts for the hydroamination of olefins. | 02-10-2011 |
